A solid weighs 4.8g in air, 2.8g in water and 3.2g in kerosene. Calculate the ratio of the density of the solid to that of kerosene

Answer 1

the weight change in the kerosene is the weight of kerosene displaced by the solid

if the solid were kerosene, its weight would be 1.6 g ... (4.8 - 3.2)

so the density ratio is ... 4.8 / 1.6

Answer 2

How did you get 1.6
